A method for transmitting a buffer size report (BSR) by a wireless node in a wireless communication system is disclosed. The method comprises receiving logical channel group (LCG) configuration information including identities of LCGs from the network; generating the BSR including octet presence indications; and transmitting the BSR to a network, wherein each of the octet presence indications indicates whether a corresponding octet is present or not in the BSR, wherein a number of the octet presence indications is variable according to a highest value of the identities of LCGs.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein each of the octet presence indications has a size of 1 bit.
3. The method of claim 1, wherein generating the BSR comprises setting at least one octet presence indication to a first value indicating that the corresponding octet is present in the BSR, when at least one LCG associated with the corresponding octet has data available for transmission.
4. The method of claim 3, wherein generating the BSR comprises setting the at least one octet presence indication to a second value indicating that the corresponding octet is not present in the BSR, when any LCG associated with the corresponding octet does not have data available for transmission.
6. The wireless node of claim 5, wherein each of the octet presence indications has a size of 1 bit.
7. The wireless node of claim 5, wherein the at least one processor is configured to set at least one octet presence indication to a first value indicating that the corresponding octet is present in the BSR, when at least one LCG associated with the corresponding octet has data available for transmission.
8. The wireless node of claim 7, wherein the at least one processor is configured to set the at least one octet presence indication to a second value indicating that the corresponding octet is not present in the BSR, when any LCG associated with the corresponding octet does not have data available for transmission.
